After applying the 19.3.2369 March 11 update, Firefox 65.0.2 and Chrome 73.0.3683.75 (latest release version of each) are now showing Avast! Web/Mail Shield Root for the issuer instead of the actual certificates for various sites including google, facebook, ebay, and many smaller sites.
The same behavior change happened after this Avast update on two different Windows 10 machines.
Before, using the February update on both machines, Firefox and Chrome would show the site's actual certificate when you clicked the padlock icon and certificate.
After the update, I can't find a pattern as to when the real cert shows and when the Avast! Web/Mail Sheild Root shows as the issuer - avast is now showing over 50% of the time. I would really like the previous behavior back in firefox and chrome. Thanks.
